I know the "add a doll" form is a bit scroll-y right now. I am still trying to figure things out. Please bear with me.
Reducing File Size
Here is a tool you can use to reduce the file size of a PNG/JPG file. If you know of a similar tool, please let me know!
What does TinyPNG do? TinyPNG uses smart lossy compression techniques to reduce the file size of your PNG files. By selectively decreasing the number of colors in the image, fewer bytes are required to store the data. The effect is nearly invisible but it makes a very large difference in file size!
