-------------------------Description----------------------
This code is characterized by the conversion of all unsightly warning to an error prompt that can be exported from the design, @ The effect is to suppress lending information. This code by default converts a picture to a thumbnail that is no longer than 150 pixels long and is saved as a new.gif. Can be modified at will when used.
This code is produced by Turtlevan (turtlevan@263.net), you can arbitrarily use and modify, can also be spread on the network, but not plagiarism for already.
