convert base64 string to .tiff image - php

Case : I have images in BLOB format in database and from database getting the images in base64 string. My code was working fine when images was .jpeg.
Code:
<?php $img = $image['PRODUCT_IMAGE']->load(); ?>
<img src="data:image/jpeg;base64,<?php echo base64_encode($img); ?>" />
Now suddenly my db administrator converted all images in .tiff format and i have to change my code to support .tiff format. I have been trying for solution but didn't find anything in this case.
In most scenarios they have .tiff file to convert example.
please have me achieve one of the following solution
Convert base64 to .tiff that some browser don't support.
Ask our DB administrator to change the format of all images.
As you guess i don't have the solution to 1 and 2. 3 is not likely to happen.

There's any way to put an image from a string (with the contents of an image) in html?

So what I want to do is to write a txt with text and image contents, and then put it in a webpage from the string (with php).
Read the file with php and get a line of the content of the txt to transform it to an image and be able to put it on an html tag.
I haven't tried anything yet, because I don't really know how to do this, or even if it's possible.
Possible duplicate: I think that it isn't because I didn't know what Base64 was so that other answer you were supposed to know it, so for doing it easier to search for people I think it's better to leave it (or not I don't really care so much).

php:
$path = <path to file>;
echo '<img src="data:' . mime_content_type($path) . ';base64,' . base64_encode(file_get_contents($path))" alt="alt_text">';
html:
<img src="data:<mime>;base64,<base64 byte data string>" alt="alt_text">
you can set an image tag to hold raw image byte data, it just has to be in base64 format.
the data:<mime>; part holds the mime, or file content type.
the base64,<base64 encoded string> holds the raw data from the image that you get from using file_get_contents($path) and then encoded in base64 format with base64_encode() function

Get base64 encoded png image from url in php

I have picture url from Facebook in jpg format. But I can manage it in another code only if it is in base64 encoded png format. I don't want to rewrite entire module.
I have tried everything I found on Internet and nothing works.
The closest I solve this is
base64_encode(imagepng(imagecreatefromstring(file_get_contents($url))));
If you have some ideas I would like to hear them.

get image, file_get_contents('image.jpg');

How to load image blob?

I have an image in binary blob field and I am unable to read.
In the database looks like this:
Yes, this is the shape of the image into text.
This and how image:
I tried several things and the only one that approximates the expected result was:
echo '<img src="data:image/jpeg;base64,'.base64_encode( $result->fields['LOGO'] ).'"/>';
Resulting in:

How can I perform the reading of the image correctly in php?

OK, you are definitely using wrong MIME type. Since you said in the comment that original image is BMP, try:
echo '<img src="data:image/x-windows-bmp;base64,'.base64_encode( $result->fields['LOGO'] ).'"/>';
or:
echo '<img src="data:image/bmp;base64,'.base64_encode( $result->fields['LOGO'] ).'"/>';
If it still doesn't work, try skipping first 8 bytes, simple substr might work here. You need to skip 8 bytes, since bitmap adds 4 bytes as header for specific image type (in your case: BM) and 4 more for file size. You can find more info on Bitmap file header here.

php reverse imagecreatefromstring

Is there a way to turn a jpg to string, reverse of imagecreatefromstring?
I have to communicate to a server which needs binary of image, i saw plenty of jpg to binary but not the other way around.

Just a shot in the dark here... No real experience with this, just my thoughts after looking through some documentation...
I see in the documentation of imagecreatefromstring() an example is given where a base64 encoded string is converted into an image. Taking that example and flipping it around might just be what you are looking for.
$image = file_get_contents('image_file.jpg');
$imageString = base64_encode($image);

imagecreatefromstring takes a string which contains the binary data of an image and turns it into a gd image resource so you can manipulate it with the gd image library. Literally the "reverse" of that would be imagejpeg, which saves a gd image resource to a jpeg image.
I guess what you really want though is simply the initial string, which contains the binary data of the image to begin with. I.e.:
$imageString = file_get_contents('image.jpg');
$gd = imagecreatefromstring($imageString);
Just skip step 2.

Base64 Encoding Image

I am building an open search add-on for Firefox/IE and the image needs to be Base64 Encoded so how can I base 64 encode the favicon I have?
I am only familiar with PHP

As far as I remember there is an xml element for the image data. You can use this website to encode a file (use the upload field). Then just copy and paste the data to the XML element.
You could also use PHP to do this like so:
<?php
$im = file_get_contents('filename.gif');
$imdata = base64_encode($im);
?>
Use Mozilla's guide for help on creating OpenSearch plugins. For example, the icon element is used like this:
<img width="16" height="16">data:image/x-icon;base64,imageData</>
Where imageData is your base64 data.

$encoded_data = base64_encode(file_get_contents('path-to-your-image.jpg'));

My synopsis of rfc2397 is:
Once you've got your base64 encoded image data put it inside the <Image></Image> tags prefixed with "data:{mimetype};base64," this is similar to the prefixing done in the parenthesis of url() definition in CSS or in the quoted value of the src attribute of the img tag in [X]HTML. You can test the data url in firefox by putting the data:image/... line into the URL field and pressing enter, it should show your image.
For actually encoding I think we need to go over all your options, not just PHP,
because there's so many ways to base64 encode something.
Use the base64 command line tool. It's part of the GNU coreutils (v6+) and pretty much default in any Cygwin, Linux, GnuWin32 install, but not the BSDs I tried. Issue: $ base64 imagefile.ico > imagefile.base64.txt
Use a tool that features the option to convert to base64, like Notepad++ which has the feature under plugins->MIME tools->base64 Encode
Email yourself the file and view the raw email contents, copy and paste.
Use a web form.
A note on mime-types:
I would prefer you use one of image/png image/jpeg or image/gif as I can't find the popular image/x-icon. Should that be image/vnd.microsoft.icon?
Also the other formats are much shorter.
compare 265 bytes vs 1150 bytes:

Check the following example:
// First get your image
$imgPath = 'path-to-your-picture/image.jpg';
$img = base64_encode(file_get_contents($imgPath));
echo '<img width="100" height="100" src="data:image/jpg;base64,'. $img .'" />'

Google led me to this solution (base64_encode). Hope this helps!
