Tubes with two or more graphic elements are usually on separate layers.
Never a drop shadow on actual tubes or any images posted in gif format.
All have been saves is PSP 5 format, so that they may be used with all versions of PSP.
The above tubes - veggie basket & pear pie were given to me by my dear neighbor. I took a picture on my digital camera & then tubed them. They made a nice graphic for the Thank You card I sent her.
