Renaming File And Retagging / Edit Image MetaData / Meta Tags?

Project:I'm building an app for personal use to rename, retag, and organize the apocalyptic quantity of images I host on my personal website. As I have been collecting funny pictures and such for several years, there is no real rhyme or reason to the file
naming conventions. Ergo, Image0001.jpg needs to be renamed to a descriptive filename, and the Metadata fields need to be filled in.The desired process will take an existing jpg, gif, png, tiff or bmp and do the following:

[1] load image into memory

[2] convert bmp files to jpgs if needed (for a smaller file size, mostly)

[3] load image tags into ImageData Structure (see below)

[4] load file data into ImageData Structure (where needed)

[5] display image and tags for user to edit (In a Picture Box and several Text Boxes)

[6] allow editing of fields and renaming of the file

[7] write the changes to the image file

[8] go to next file.

Example:

[1] Load Image0001.jpg. Populate ImageData Structure fields.

[2] Type in Description: "lolcat ceiling cat sends son".

[3] ImageData.FileName changed to "lolcat-ceiling-cat-sends-son.jpg".

[4] ImageData.Name, .Keywords, .Title, .Subject, and .Comments changed to "lolcat ceiling cat sends son".

[5] Save file with new filename and save all new tag fields.

(Later, I will also be using SQL to build a referential database with links to the online copies of these files to allow for searching by keywords, subject, filename, etc, but that's another layer that's much easier than this one. At least to me.)

Problem:So far, several days of research have yielded almost no measurable progress. Information has apparently been inexplicably hidden behind a bunch of unexpected search keywords. Current Code as is:

Imports System.IO
Imports System.IO.Path
Imports System.Drawing.Imaging[code]........
