    Yeah, rotating it horizontally (or vertically, I guess).

    If the lights were in the same place, then you'd still be able to see the different reflections off the coin... or similar at least.

    I have a mid-low range but new-this-year LG K7. I think the 1.5GB of RAM is the limiting factor; I accessed this thread via wifi and had no bandwidth problems.

    It's certainly no problem on my, um, slightly more powerful home computer. :)

    LOL, it does not help that the images are just over 20MB each. Now if we could just somehow squeeze this kind of quality into a file size of under 1MB, then we would be defeating the laws of digital physics. LOL :)

    What are the filesizes of your original images? Should be trivial to get a 600px image well under 200kb without losing any apparent quality.

    That depends on the original you are referring to. The master GIF is 1215x1215 pixels by 115 frames and 131 frames for the obverse and reverse. The GIF settings are set to use 256 colors. I think the issue is the number of frames.

    If we could incorporate MGPEG2 compression into an animated GIF, that would help significantly.

    I was thinking that you have to establish a succession of individual frames which are software-blended to make up the .gif, and the smaller each of those frames is, the smaller the final output file will be. Halve the size of the original - you built it at 1215 but are presenting it at 600 - and the final version should be rather smaller.

    It is. The 1215 version of the reverse file is 105MB and the 608 version is 20MB just just a bit over 1/5th the size for a 1/4th reduction in overall resolution. Now the 1215 version of the obverse file is only 70MB and the 608 version is 21, why the discrepancy, I don't know. One would think that the Obverse file should be smaller as it's 16 frames less than the reverse. The Master 1215 obverse is smaller than the 1215 reverse, but why by 35MB is a mystery to me. Then once reduced, the 608 Obverse is 1MB larger than the reverse. Obviously there is some compression algorithm at work here. I just wish it was a number slider based one like that used in JPEG. I know varying the dithering percentage would help, but I just don't know that much about GIF's. This is where further study will help me.
