when it first loaded is of low quality (slightly pixelized), then after awhile, the images becomes hi-quality

Sounds like either .png or .jpg, properly handled, qv.

the images are loaded very fast!

• Define "very fast!"
• Apt to depend on many variables: is the image file local, on a network, on a remote server?

how do i achieve this using perlmagick and tk canvas? :)

• Have you read the relevant documents?
• Have you searched this site?

And if you show us what you've tried, we may be able to offer more specific help. But the Monastery is NOT a free, code-writing machine.
