i try

so download fototagger at this address http://www.fototagger.com/

is free and try fototagger

open a foto.jpg insert tag and save whit foto2.jpg

after saved if you do double clik over foto2.jpg , you can look a normal foto whit out tag

but if you open foto2.jpg whit fototagger you can see a tag saved before.

if you open foto2.jpg whit exadecimal editor like ultraedit , you can look a code in javascript of fototagger program

i wanna insert the javascript whit out fototagger but whit autoit , is possible? ??

Considering no one knows what you are talking about, you should try to accomplish this yourself and post the code you have when you hit errors.

As the format specification is not available on their website it will be hard work to determine how to store the tag information.

[faustf 18]

do this procedure for understund

software required

1. http://www.fototagger.com/download.php?product=latest

2. ulrtraedit software

3. use one foto in your pc , (i call foto.jpg)

instruction: open foto.jpg with fototagger insert a tag . save your foto whit foto2.jpg name

open foto.jpg and foto2.jpg whit ultraedit

look a difference

the difference are this code :

Unfortunately I don't have the time to download ultraedit, play with your pictures and present the solution.

You need to determine where to insert this xml text. Is it at the end of the picture?

If you know where to insert simply use FileOpen, FileRead, FileWrite, FileClose to create a copy of the picture.

[faustf 18]

no insert not at the end but use esadecimal marker is FFDB put the code after FF and last is FFDB , whit file FileOpen, FileRead .... is possible find esadecimal marker ??

[water 2,119]

Sure. Read the whole picture into a variable using FileRead. Then use StringInStr to find the position of the marker. Split the variable in two parts at this position (Stringleft, StringMid) and combine all 3 parts to a new variable and write it to a file.

[faustf 18]

i tryed to do this

only for understund

Local $file = FileOpen("_DSC0195.jpg", 0)
; Check if file opened for reading OK

; Read in 1 character at a time until the EOF is reached
Local $chars = FileRead($file)
; If @error = -1 Then ExitLoop
MsgBox(0, "Char read:", $chars)

FileClose($file)

but messagebox giveme only first 4 carachter

[water 2,119]

Use

MsgBox(0, "Char read:", BinaryToString($chars))

to get the hex representation of the string.

[faustf 18]

but give me the same 4 carachter

[water 2,119]

Change the first line to

Local $file = FileOpen("_DSC0195.jpg", 16)

so you read the file as binary.

[faustf 18]

the same

[water 2,119]

I used this script and got a long, long display of characters.

Local $file = FileOpen("P1000545.JPG", 16)
Local $chars = FileRead($file)
MsgBox(0, "Char read:", $chars)
FileClose($file)

[faustf 18]

but whit this MsgBox(0, "Char read:", $chars) appear 0x0......... much more

[water 2,119]

That's the hexadecimal representation of your file. It's the only way to read the file - else it will stop at the first 0x00 character. That's why you see just 4 characters.
