Welcome to TG Design-maker, and thank you for participating in the challenge. Unfortunatel I cannot see your image as the Attachment is invalad. If it's a size issue, click on the ? in the upper right hand corner on the manage attatchments page or scroll down and click on manage attatchments to see size and types allowed. Check the dimensions and save your image as an appropriate file type and size, I usually save as png. If it's another issue let me know and I or someone will help.
Please repost your image.
