As this topic comes up on a fairly regular basis, I though I'd post an update.
Having just acquired a new laptop for work a few weeks ago, running Windows 7 Enterprise, I again needed to download an image resizer tool. It's no longer a Microsoft tool - in fact I don't think it's available from Microsoft at all. However these guys in the UK have developed an XP Powertoys adapted tool that works on all the new 64 bit versions of Windows for pretty much all PC platforms.
Having just installed it today, I can verify that this is a supper simple tool for resizing photos on your lap top/ PC and best of all it's simple, fast and Free! Right click on the photo, choose one of 4 resizing options and its done - no software to upload, no fuss. The small and medium select sizes will usually take a file and shrink it below the 250K limit we need for uploading/ posting on this site.https://www.digitalred.com/support/wind ... -resizing/
