[solved] Transparent image background

[wert790]

Hi!
I'd like to have a transparent product image background instead of the ordinary white one. I understand i have to make changes to images.inc.php file, but i just can't get it to work.

Do anyone know where i can get a finished, working image.inc.php file which creates png-files with transparent background?

Thanks alot!

Hi!

I been trying this also but instead i put in the same color as the background witch is perfect for me - in rgb color (use photoshop to convert your values).

Although this won´t help you if you have an image as the shop´s background but anyway - for this i have no solution.

Here are the changes i did made (the 70 numbers) on line 157 in latest stable PS version:

$white = imagecolorallocate($destImage, 70, 70, 70);

Hi!

Unfortunatly i have a gradient picture as a background and hence cannot use your method. Thanks for the answer anyway !

Anyone else with a suggestion?

Use the PHP function imagecolortransparent() to set the color you want to be transparent.
Remember, you cannot set JPGs as transparent so you need to save as PNG or GIF and modify all your images to that type.

Intresting!

Is it really not possible with jpg?

Nope, JPEGs don't support transparency. GIFs support transparency and PNGs support semitransparency.

PNGs support semitransparency.

PNG's support full and alpha transparency with alpha channels.

Problem solved, thanks for your feedback. I used a ready-made images.inc.php found in this thread: http://www.prestashop.com/forums/viewthread/23714/P15/third_party_modules/images_dot_inc_dot_php__made_to_use_png ( the one posted by goums, creds to him ).

anaway , if someone does not want to change code or is not confident with his php skills there is a module in the prestashop ADDONS section that solves the issue automatically:
