Badmouth, I know what is causing your album art issue. The large file you sent me, the 1 MB one, is not a jpeg file at all, it is a bitmap file. I'll try to explain without sounding too nerdy. An image editing program like paint is fairly smart. It loads the raw data from a file into a buffer, and analyzes the buffer to determine what it is dealing with. The label control I am using isn't that smart. It looks at the file extension to determine file type, then goes to one of several different dll files to determine how to handle that file format. In this case, you told it the file was a jpg when it wasn't, so it went to the jpg dll. Since the jpg dll couldn't read a bitmap file, nothing loaded into the label. When I changed the file extension to .bmp, the file showed up fine. This won't work for you, however. At least not yet. You see, I forgot to provide support for pic files other than jpg in the initial release. This was just an oversight, I forgot to add the appropriate DLLs when I was building the install package. This will be rectified in the next release. This also explain why your paint program shrunk the file by 90% when you loaded it and saved it without changing. You told the program to save it as a jpg, so it did, and that included applying jpeg compression to it.
Ego, it's funny how one person's passion is another's poison. The number keys are one of the primary reasons I built this to begin with. I found in using SK Juke, that I was always using numbers to enter the track, since my fingers are large and not nimble, and that I had to attach a physical keyboard to my jukebox PC since trying to double click my touch screen was more annoying than not. Also, some of the things I left out because I found them off-putting and distracting, like the weird special effect bars and wavy lines while the song is playing, are things you say you miss.
Today I am going to see about adding support for 4 digit album numbers. This will be a configurable option, so if you have a small (under 1000 albums) collection, you can still use 3 digit albums. This will also mean that for large collections, the Options screen will be "0000". I will also try to add Move to Top and Move to Bottom buttons on the track list screen. I also appreciate the thought of sharing the load, and if any programmers want access to the source, I will gladly zip it up, post it to my Mediafire account, and send you the download link. But any new person would need a few weeks to get familiar enough with the code base to help, especially if they have not used Qt before. Easier to do things myself for now.
