1) Paste the following expression in your notebook.

FrontEndExecute[
  FrontEnd`HelpBrowserLookup[
    "RefGuide",
    "Export"
  ]
]

2) Evaluate the expression you just pasted.  This will open the reference
guide entry for Export[] in the Help Browser.

3) Scroll to the end of the entry and locate a cell that reads "Additional
Information."

4) Click on the triangular dingbat at the left of this cell to expose a
sizeable amount of material.

5) Locate the subsection that is headed "GIF".

6) Note the option named "Loop".

This is what you are looking form.  Note that this option is a suboption
to the option ConversionOptions.

Export[<file name>, <graphic list>, "GIF", 
  ConversionOptions -> {"Loop" -> <value>}
]

You can use the Log*Plot[] functions that are defined in the Standard
Package Graphics`Graphics`.

FrontEndExecute[
  FrontEnd`HelpBrowserLookup[
    "AddOns",
    "Graphics`Graphics`"
  ]
]
