When the snitz forum tells it to display a users picture, it sets the height and the width to 150 without knowing the users existing picture height and width. this can cause the picture to get stretched and not look right. there is a function that can be used to generate the height and width and not strech the picture.
response.write "<img src=""graphic.gif"" " & ImageResize(strImageName, 150, 150) & ">"
the first 150 is the width, and the second one is the height. this should fix the problem

this looks more like a Design Request With Code to me, Gor.. |

Hey brad,
I just tried it and there's no such ImageResize function. Where did you read about it?
In order to resize the picture dynamically I'm using ASPIMAGE server component that does this on server side.

Brad,
If you had read the article a bit closer, you would have seen that you didn't tell the whole story.
In the article they also give the code for the function ImageResize that is needed to get this to work. 
function ImageResize(strImageName, intDesiredWidth, intDesiredHeight)
dim TargetRatio
dim CurrentRatio
dim strResize
dim w, h, c, strType
if gfxSpex(strImageName, w, h, c, strType) = true then
TargetRatio = intDesiredWidth / intDesiredHeight
CurrentRatio = w / h
if CurrentRatio > TargetRatio then ' We'll scale height
strResize = "width=""" & intDesiredWidth & """"
else
' We'll scale width
strResize = "height=""" & intDesiredHeight & """"
end if
else
strResize = ""
end if
ImageResize = strResize
end Function

What about the gfxSpex function call? Doesn't look like a built in function to me. |

i use a simple way to fix this and i suppect it only work in IE but not with other browsers (i cant install netscape on my system to test this, the silly thing crash my puta grrr...).
If you opmit the height = ".." tag inside the image tag and only specify the width tag then IE will auto-scale the image for you correctly.
You can see the what i mean here: http://eve.121host.net/forum/topic.asp?TOPIC_ID=18&FORUM_ID=9&CAT_ID=5&Topic_Title=What a wonderful site%21&Forum_Title=Test Forum
Isis's picture scaled correctly on topic post as well as in her profile if you look at it.

could someone please test this to see if this would be a problem in other browsers? maybe even a little javascript to check the users browser and if its ie then it removes the height, any ideas?

I am trying to get this code to work with my database. However, it keeps ignoring my resize.
<%response.write( "<img src=" & rsRecordSet("thumbnail") & ImageResize(strImageName, 100, 75) & ">")%></a>
