Image Handler 4 (for v1.5.x) Support Thread

[pasi]

Tried to search but got too many results to go through them all...

Anyway, the problem is that some images are in GIF format. JPG images are resized correctly, but the GIF images aren't resized at all.

Before I go deeper into checking what is wrong, I wanted to ask if IH4 actually supports resizing GIF images, or if there is any known "issues" or "fix" to this.

Greetings IH4 experts, I have a general question about this mod. Will it help reduce the amount of server overhead my site is generating? I'm being pestered by my hosting company to reduce my CPU usage. I am on a VPS. Running my site through various website speed check sites, the biggest thing that keeps popping up negative are my images.

Here's my site if anyone wants to take a peek:

IH4 as the opening thread (and readme) states will optimize your product and category images.. However, if you have other optimization issues on your site, or images in other places on your site (non product/category images) IH4 will not resolve those issues.

If you are trying to use different image formats on the same product, then you will have issues. (all images for a single product must be the same format) And if I remember correctly IH4 does NOT support GIF files..

There are issues in many cases related to resizing .gif images, and a lot of on-the-fly image resizers either can't resize .gifs, or don't because of issues. The biggest issue I've seen resizing .gifs is that since they are already in indexed color mode, you almost always get really bad looking images. In addition, there are copyright issues with publishing .gif images on the web that you should be aware of...

I can't speak as to whether IH4 should handle .gifs for you or not, but I would strongly encourage you to replace those .gof images with either .png or .jpg versions, which will address the issue you are seeing and the problems with resizing .gifs.

Yep IH4 supports GIFs, an example from my test site is the original GIF image here as uploaded



and the product listing here


where image handler is, well handling it

As for any patent issues with gifs, I am fairly sure those patents expired 10 years ago
