first I would like to thank You for all Your work!!! Great stuff!
Now - I am testing this plugin on new MBP (but the same issue is visible on iPhone 4s). The web is: http://fotografie-realizaci.cz (Choice theme from Kriesi.at).
Strange thing happens - at least for me :-) Slideshow image first loads in high resolution, but than it falls back to low-res and gets blurry (after second or so). I tried both server and client ways, turned off responsiveness, debug mode (its ON now). Uploaded various resolutions, but its always the same.
When I open the image in new window it shows in high-res (and downloads as well), although the path shows low-res version (http://fotografie-realizaci.cz/wp-content/uploads/2012/07/Homepage-3-990x600.jpg).
So...I am kind of lost here...what am I doing wrong?
Just to be clear - the logo is uploaded already in high-res and constrained with css (so no relation to the plugin).
