The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Resize jpeg or gif for already uploaded images

Asked by meedjmom in Active Server Pages (ASP), Web Images, Images & Photo Software

Tags: aspupload aspjpeg resize images thumbnails

I currently have a working version of ASPJpeg that allows me to take an image (already uploaded to the server) and create a thumbnail version of that image and store it in a separate folder on the server. For jpegs, everything works great. However, I need it to work for gif images. Currently, if I try to resize a gif that has a transparent area, the current setup doesn't handle the transparency well. I have read at Persits software that the ASPJpeg function now has gif capability but the gif management object is handled separately. In other words, I need to know that I am working with a gif image before using it.

My problem then is how to identify whether the image that I want to resize is a jpeg or a gif. As a reminder, I have already uploaded the image to the server and that can't change. And, after identifying whether it is a jpeg or a gif (the only two types of image that I allow), then to set up the code to handle jpegs using the 'regular' ASPJpeg method and the gifs using the special gif management that comes within the newest version of ASPJpeg.
