No PNGs please. They're not really suited for screenshots. Use JPEGs at medium-high or high quality. PNGs of that size take too long to load.
That first image is 6.1 MBs. A JPEG could mash that down to probably <400 KB.
Short of using a program such a photoshop to change them to JPEG's, how would I get them to be saved as that instead of BMP's, which is how they are currently saved in my New Vegas folder.I don't have a clue as to how they are getting converted into PNG's after uploading to Imageshack. :shrug:
