Title: optimizing graphics seem to be overridden somehow
Post by: llegrand on May 05, 2015, 05:49:27 PM: I am working in a new clean install of 1.2.1.

It seems there is something that is overriding my image file sizes. I have optimized my images to increase my page load speeds, but something seems to be re-doing them.

Here's an example, I uploaded a product image of 300 x 300 optimized to 25.7KB, but when I check image sizes on the home page it comes up at 250 x 250 for 244.84 KB and all the images on the home page regardless of what I have for the upload to the resource library seem to use that size. If i check the resource library it is 100 x 100 for 39.28 KB

What is re-sizing the uploads? I have not encountered this with previous versions so am "concerned" with the 1.2.1 as it is negatively impacting my page load speeds.

After doing a little more testing I am only having the issue with .png images, jpg is working correctly. So now I am more confused! Should we not be using png?

thanks.

i guess issue is in core/lib/image.php.
Can you post url of your png?

Look in the latest products

blue image png uploaded 500 x 500 77 KB in resources shows 100 x 100 thumbnail 39.28 KB Home page 250 x 250 244.84 KB

red image jpg uploaded 500 X 500 57.5 KMB in resources shows 100 x 100 thumbnail 13.07 KB Home page 250 x 250 55.5 KB

this is just something I don't understand.

Please check attached file

Post by: llegrand on May 06, 2015, 12:03:35 PM: I have checked that file against the one in the installed cart (a virgin install with nothing changed in the files)using a compare tool.

They are identical. So what's next?

By the way I tested this on the demo installed also, and it has the same result.

To test you need:
- replace core/lib/image.php
- clear thumbnails via admin->system->cache->clear images
- open storefront ( your thumbnails will be recreated)
- check size

Post by: llegrand on May 06, 2015, 12:56:26 PM: okay, have done all that - actually did it three times to be really sure I used the correct file

I am getting the same size on the home page - I have added one more - the Abantecart Logo, and it behaves the same.
It seems is does not matter what size the image is, the 250 x 250 goes to the same size on png files. 244.84
