when you use photobucket you can only add PNG files or JPG's there not tubes, so you have to go somewhere else to load them for posting or use MSN storage
I love using PNG file it is just a good as saving them as a tube file
we can start posting every thing as PNG file that way you get to see it and there would be no downloading
just the matter of right click and saving, but if the tubes have more than 1 layer (example) you have a tube with 3 layers a image layer, flower layer and copyright layer if you save it as a PNG file then you have to merge all the layers before saving it so you would not be able to adjust the layers later
but a tube with a single layer woould be fine to save a PNG file
hope this helps
