Hi All,

Preliminary results using the BPEmbededArt plug-in, before the crashes reported in post #36 above.

I used copies of a single mp3 and 2 versions of the same JPG image:

Image A = 160x160 pixels, 96x96 dpi, 24 bit color, 85 compression quality, 5,532 bytes file size

Image B = 300x300 pixels, 96x96 dpi, 24 bit color, 85 compression quality, 14,465 bytes file size

Using MediaMonkey to embed increased the mp3 file size by 4,096 bytes with Image A (1,436 bytes < the source image) and 14,336 with Image B (129 bytes < the source image).

Using BPEmbededArt v.1.0 & v.1.0.2.6 to embed increased the mp3 file size by 4,224 bytes with Image A (1,308 bytes < the source image) and 14,464 with Image B (1 byte < the source image).

I did not notice the "BPEmbededArt.ini" file until after I had switched back to v.1.0. I assume both versions were using the same compression quality value.

So it seems that both methods further compress the source image somewhat. MediaMonkey does it a little more, especially with image B.

I want to use the smallest image size possible to suit my needs. The 160x160 image has acceptable quality at all the display sizes I normally use, but becomes pixelated at the maximum display size I sometimes use. The 300x300 image has acceptable quality at this maximum display size, so it also looks a little better than the 160x160 image at the smaller display sizes.

I don't know much about image formats and don't understand why Image B's file size is not larger than it is (since 160x160=25,600 & 300x300=90,000), for the same picture at the same dpi, color depth, and compression levels. Must be some JPG compression magic.

Would I get the same quality results with Image A if it's dpi was larger?
