Adding a Web Part to the SharePoint Web Part Gallery

This is probably better documented elsewhere, but I’m making a note of it since it is so handy.

1.       Create your web part and save it. If you are simply customizing a content editor web part, or the like, you can generate it this way: Select the Site Webpart Menu (the small triangle in the right-hand corner of your web part) and select Export.

2.       From your Site Actions > Site Settings > Modify All Site Settings

3.       In the Galleries column, select Web Parts.

4.       Upload the web part you created in step 1.

5.       Voila, you have made your web part available in the Add Web Parts dialog box.
