I think FireFox 16 was the last one, that could directly save TW. Now we are using TiddlyFox [1] AddOn to save a file TW with the latest browser. You could also use TiddlyDesktop [2] with TWc.

AttachFilePlugin uses the
"netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");"
function, which has been removed. It doesn't matter, if you want to read or
write ... accessing the local file system with these functions doesn't work
anymore.

Atm. You can't.

Re: [tw] Re: Chrome, white and access control
Hi again... not sure why you need to embed the graphic(s). Obviously using the [img[...link ]] function lets you display and play with a graphic inside a TW...it is a link to an imageyou can add extra control with Erics ImageSizePlugin...and he even has a ImageMapPlugin that magically allow you to create clickable imagessuch as maps... BUT all this uses links to existing files (...online or offline)links to images not images embedded...its the embed functions that got stuffed up by these security questionswhich means that great plugins like LocalDirectory LaunchApplication, AttachFillePlugin...don1t work anymore - with medern, updated browser versions. Actually this brings up a small point. Especially in Erics site there are many great plugins that used to work, but now dont work (with recent browser versions)...and it not clear to newcomers which or why..maybe we need a short note in these tiddlers noting that they have this limitation/restriction. just a suggestion Skye Em terça-feira, 18 de março de 2014 09h28min51s UTC-3, Anton Aylward escreveu: > > On 17/03/14 09:49 PM, PMario wrote: > > > > > > How can I use Eric's tool if I cant *READ* the file? > > > > Atm.

Actually, *use* of embedded images still works just fine...
AttachFilePluginFormatters extends the [img[...]] syntax to allow reference
to embedded "attachment tiddlers". The problem is in *creating* NEW
attachments, which needs to read *binary* file content from the local
filesystem. That is the part that is blocked by the browser.
However... there IS a way to *manually* create attachment tiddlers
First, take a look at:
http://www.TiddlyTools.com/#AttachFileSample
The format of this tiddler uses standard TiddlyWiki section syntax, like
this:
--
!usage
{{{[img[AttachFileSample]]}}}
[img[AttachFileSample]]
!notes
example of encoded data attachment
!type
image/gif
!file
./images/meow.gif
!url
http://www.TiddlyTools.com/images/meow.gif
!data
data:image/gif;base64,R0lGO...
--
The sections are labeled "usage", "notes", "type", "file", "url", and "data"
The "type" section defines the MIME type for the attachement (e.g,
"image/gif", "image/png", "image/jpg")
The "file", "url" and "data" sections are options, but at least ONE must be
present. The "file" section is for local filesystem references, the "url"
section is for remotely stored images, and the "data" section is for
embedded base64 encoded binary (e.g., the image file contents) To display
the image, AttachFilePluginFormatters first tries the embedded data (if
any), then the local "file" reference (if not blank), then the remote URL
(again, if not blank). If
You can create your own attachment tiddlers manually by making a copy of
the AttachFileSample tiddler and then hand editing the information it
contains. The only tricky part is generating the base64 encoded image data
itself. There are several easy-to-use "base64 image encoder" tools online.
Typically, you just upload your image and it returns the encoded text
result. You can then copy/paste that data into the appropriate place in
the attachment tiddler. Note that the data section of the tiddler always
starts with "data:image/gif;base64,", followed by the actual data.
Hopefully, this will give you enough to get started... let me know how it
goes.
