I found many times the PunyPNG and Smushit websites either timed out or returned 500 errors. While I realize this is not the tool's fault, it does limit the usefulness.

In addition, while working with Assembla as a code repository, it will often delete images that do not need optimizing. Those that were optimized are saved properly. Can't seem to see a pattern, but once again this really limits the usefulness. If you optimize a folder, you have to figure out what images are deleted that should not have been from others that were optimized.

This is a great tool. I wish more Web developers would think about how much bandwidth we are wasting.

looks nice but it seems it screws up my positioning of team explorer and other stuff.. I constantly have to move the windows to what I'm used to.
Once uninstalled the problem stopped?

Anyone else with this problem?

(oddly I didn't find a way to reply.. maybe I overlooked it :) )
The Team Foundation window, pending changes,... did a new install and now it's working fine.. must have been a Visual Studio hiccup :)

Programatik olarak eklenen bazı resimleri görmüyor, fakat genel olarak kullanışlı bir uygulama.

So useful...Love it

Awesome, awesome, awesome. The optimization is great, but my favorite thing about this is the mouseover thumbnails of images in Solution Explorer.

Sounds very promising, but I couldn't get it to work.

This is probably because you're image files are under source control. Check them out first and then run Image Optimizer. I'm working on an update that will check out the files from source control automatically

Embedding images in CSS is not working for me, but great anyway.

That feature was moved to the Web Essentials extension

    • Hello, I've noticed, smushit library has moved, and thus optimization is not further possible.
      Every time png is processed, i get:

    1 Posts | Last post September 08, 2014
    • Hi Mads,
      I know, optimizing SVG graphics/images is something complete different and difficult in comparison to PNG & Co, but ... any chance to integrate a kind of TinySVG?
      Kind regards,

    • Works great, but having an issue that the optimiazation adds some artifacts for some png images that I dont want. (background images with solid colors changing from dark to light grey)
      Can I prevent it from optimizing a few images in the solution?
