i was looking at personalizing my Opera, so i went on to Themes, there are two ways you can do this, you can either choose a preloaded number of photos(pictures to download from the Opera store), or upload your own photos and pictures.
First i tried the preloaded ones from the store, clicked to download and nothing happened, i tried various pictures that Opera offered but got the same result from them all, so i then decided to upload my own, but every time i tried to do this, a message would come up saying "cannot download due to unsupported file type" ?? I've never encountered this before, whats happening or not happening as in my case ? please help.

in reading all the features that Opera had to offer, i came across Opera Turbo, and read just how fast and efficient it made the normal Opera browsing experience, once enabled i then went on to browse the internet only to have a window pop up stating: Loading of background tabs is delayed because Opera Turbo is enabled. ???? what exactly does this mean, also i had previously uninstalled Opera because it kept on crashing after taking ages to load a web page, is there any connection.
