Which PNG Fix will work in this condition?

I'm working with client's CMS and it's adding images like this and i can't change t开发者_开发百科his.

I tried IE7.js but it's not working

<img src="~/imagefolder/CF88B05B445A4D008806C8B3E2830679.png?w=400&h=300&as=1" />

Unless whatever code runs behind imagefolder dislikes additional, unknown arguments, you might be able to trick the IE hack into thinking it's a .png:

<img src="~/imagefolder/CF88B05B445A4D008806C8B3E2830679.png?w=400&h=300&as=1&dummy=.png" />
