340656 - Large Images confined to smaller sizes via <img> causes browser to go dead slow

Status: RESOLVED DUPLICATE of bug 163975

(Firefox :: General, defect)

Description

[Colin B Maharaj]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.4) Gecko/20060508 Firefox/1.5.0.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.4) Gecko/20060508 Firefox/1.5.0.4

I was developing a web site (localhost) and had an image that linked to a page. The images was scaled down to 200 px high via the <img> tag parameters. 
Also I was thinking it was actually 180px or 220px high. The fact is that I forgot to scale the image to a resonable loadable size on disk (150px X 200px) and mistakenly left it at 1024px X 800px, it appeared ok, thinking that it was actually the scaled image I thought that it was, but now the browser began to crawl and I could not scroll down the page without considerable effort, and the rest of the PC began to crawl as well.

IE handles this well and does not seem to try to rerender the image (or whatever Firefox is doing) constantly.


Reproducible: Always
