CF8: CFIMAGE and CFFILE upload

[TomSchober]

I am uploading a decently large image (3-4mb) via CFFILE.

<cffile action="upload"
filefield="file"
destination="#ExpandPath('\')#gallery\images"
nameconflict="makeunique"/>

Using the CF Function ImageRead, I am reading that file back into memory to do a ImageScaleToFit to create a thumbnail.

The problem is, ImageRead is SO SLOW! Is there anyway to read the image directly from the fileField of the upload instead of writing it to disk and then re-reading it back into memory?

CF = server
<input type='file'> = client

no, there is no way to do what you want with just CF.

It seems a waste to have the image data in memory from the http request, have to write it to disk, and immediately read it back into memory. It's a major bottleneck. Any other suggestions outside of CF?

it's not a waste, it is just how things work.
cf has absolutely no idea about what's going on the client's machine.
are you sure it is imageREad that is "slow"? or maybe it just takes a
while for you to upload your file?

maybe some java applets or activeX controls can do it directly on client
side.... don't know of any though...
