plugin doesn't work

this plugin has never worked for me. I guess if it were like that for everybody it would’ve been retired long time ago. I tried on different sites it still doesn’t work. I install, enable the widget, click add image and that’s it. it keeps on spinning endlessly until I decide to quit. I like the fact that it allows you to upload but the uploading never seems to work. any assistance will be appreciated. souleye
