How can I upload Animated .gif without resize ?
Posted: Mon Apr 28, 2014 10:22 pm
Hi All.
I would like to upload animated GIF images for the product image ,Is this possible with OpenCart. 1.513 upload without resize ?
I search the forum and it is difficult to find the solution.
Method one :
Another workaround could be to edit your "catalog/controller/product/product.php". Find the following line (around line 179):-
And replace it with:
This will then use the "original" image for the product thumbnail, rather than a resized image.
But I get nothing and blank ,no mainimage when I 'm using above CODE ??
Method Two
http://forum.opencart.com/viewtopic.php?t=24967
Description: The current image library properly handles resizing JPEG and PNG (including those with alpha) correctly, but fails to preserve transparency with GIF images. This patch fixes that.
In Method Two , I confuse the above code ....Is it correct ? Can I use it ?
I just want to upload Only GIF FORMAT Image to completely bypasses the image resizing function ! Can anyone Help Me Please !!!!
Thanks
Ken
