Php photo gallery TWG | JFUploader | TWG Flash upload | WFU | Forum

Hi,
I'm just wondering if there is PNG support in this gallery? I would use jpg but it's for a Pixel art forum, and jpg makes things go all artifacty, so we'd rather use PNG because of it's size and quality. BMP is too large.

I'm quite sure there would be no licensing issues. If I'm right, PNG is open source or something like that.

Thanks for your time.

Right - actually not a problem - but I use png for all kind of images you can store in the folder like folder images, private images , watermarks ...

But actually it would be quite easy to use renamed png's. There has to be some changes in ~ 10 places to make this possible.

What changes would I have to make, and where? Is there a help on it?

Thanks for your time!

Matt

it would be in the imagefunctions.inc.php

there you find something like
$src = imagecreatefromjpeg(

where the pictures are loaded.

before you find getimagesize in all of this functions.

this returns an array with the size [0] and [1].

[2] ist the filetype - You have to chechk this and then you can open the image with imagecreatefrompng

I think only 5 changes ...

but the output will still be a jpg.


at the end the file would be written - you have to change Imagejpeg to ImagePNG (depending on the input file).
but still with the jpg filename - the browser don't care - but not sure what putimage makes ...

lot's of small changes - you can try if you like .

Sorry, but I'm not sure I understand what I need to do.
Could you be a bit more specific? I'm not a PHP coder.

Sorry for all this.
Thanks again,

Matt.

then it's quite hard .

1. you have to use a png that has the extension jpg.
2. check which filetype is it really (getimagesize [2])
3. use the png function instead of the jpg function.
4. store the image as png and not as jpg (depending on the filetype).

Aaah, do you think you could make an example, if you are not busy?

Once again, I'm very sorry to annoy you like this.

Thanks,
Matt.

send me an email - i have made this change in the main resize function of twg. you would simply have to copy this to the other places where it is needed .

/Michael

Thanks very much! I'll e-mail you now!

Thanks for all your help.
Matt.
